A book about calligraphy knowledge.

I recommend Bai He, the Appreciation of Calligraphy Art edited by Yan Zhenqing.

Shuo Wen Jie Zi is a book that introduces the evolution, appreciation, history and course of calligraphy in China.

If you want to know something about calligraphy, I suggest you don't read hard pen.

Because China's real calligraphy is brush calligraphy.

Hard-pen calligraphy just evolved from China's calligraphy, and there is nothing to see. In addition, some documentaries explaining calligraphy can be downloaded online, such as "History of Chinese Characters" and "Exploration and Discovery".

Han Mo Chunqiu, etc.
